Why the generated C codes have "b_"?

Hello everyone,

Just new to the forumn, please forgive me if i raised up the question in an improper way.

Recently, I am using MATLAB coder to generate C codes. But in the generated codes, I realilzed that some variables have b_ prefix.

For example.

start_point = 1; % this is start_point

Then, the generated codes would look like:

/*  this is start_point */
int b_start_point = 1; 

I am not pretty sure why the varialbe "start_point " has "b_" in front of the variable. Since it is the first time that it is defined, and also, there is no "start_point" in the C code, which means that it is not already exist.

Anyone can give me some clue about why it happens?

Thanks a lot.

it is possible due to variable name clash. That matlab coder has to rename that variable to ensure it is building successfully. NOT sure myself...
